Sum multiline textbox values

Hi,
If I select the values from combobox, how do I sum the multiline value in textbox1 and get the total value in textbox2 ?
Private Sub ComboBox1_SelectedIndexChanged(sender As Object, e As EventArgs) Handles ComboBox1.SelectedIndexChanged
If ComboBox1.Text <> "" Then
TextBox1.Text &= ComboBox1.Text & vbCrLf
End If
End Sub
Thanks

Private Sub ComboBox1_SelectedIndexChanged(sender As Object, e As EventArgs) Handles ComboBox1.SelectedIndexChanged
If ComboBox1.SelectedIndex <> -1 Then
TextBox1.Text &= ComboBox1.Text & vbCrLf
If TextBox2.Text <> "" Then
TextBox2.Text = CStr(CSng(TextBox2.Text) + CSng(ComboBox1.Text))
Else
TextBox2.Text = ComboBox1.Text
End If
End If
End Sub
If I where you I wouldn't use a multiline textbox but a listbox instead then you can just do
If ComboBox1.SelectedIndex <> -1 Then
ListBox1.Items.Add(CSng(ComboBox1.Text))
TextBox2.Text = ListBox1.Items.Cast(Of Single)().Sum().ToString
End If

2. This is the complete code, add it into the Script Editor Web Part and save.
<script type="text/javascript">
ExecuteOrDelayUntilScriptLoaded(retrieveListItems, "sp.js");
function retrieveListItems() {
// Create an instance of the current context to return context information
var clientContext = new SP.ClientContext.get_current();
//Returns the list with the specified title from the collection
var oList = clientContext.get_web().get_lists().getByTitle('CustomListName');
//use CAML to query the top 10 items
var camlQuery = new SP.CamlQuery();
//Sets value that specifies the XML schema that defines the list view
camlQuery.set_viewXml('<View><RowLimit>10</RowLimit></View>');
//Returns a collection of items from the list based on the specified query
this.collListItem = oList.getItems(camlQuery);
clientContext.load(this.collListItem, 'Include(Title,MultipleText)');
clientContext.executeQueryAsync(Function.createDelegate(this, this.onQuerySucceeded), Function.createDelegate(this, this.onQueryFailed));
function onQuerySucceeded() {
//Returns an enumerator to iterate through the collection
var listItemEnumerator = this.collListItem.getEnumerator();
//Remove div tag use a regular expression
var reg1 = new RegExp("<div class=\"ExternalClass[0-9A-F]+\">[^<]*", "");
var reg2 = new RegExp("</div>$", "");
//Advances the enumerator to the next element of the collection
while (listItemEnumerator.moveNext()) {
//Gets the current element in the collection
var oListItem = listItemEnumerator.get_current();
alert(oListItem.get_item('MultipleText').replace(reg1, "").replace(reg2, ""));
function onQueryFailed(sender, args) {
alert('Request failed. ' + args.get_message() + '\n' + args.get_stackTrace());
</script>

Hi Joe,
According to your description, did you want to display the TotalSold value of “Parka” in textbox23. Please refer to the following expression:
=Sum(IIF(Fields!FieldName.Value=”parka”,Fields!TotalSold.Value,0))
If there are any misunderstanding, could you please post you dataset with sample data, and the screenshot about your report design?

Assigning a textbox value

Hi,
I tried assigning textbox value to a variable.Am getting an
error Access of undefined property txtid.
Follows my code:
public var ptyID:String;
ptyID=txtid.Text;
Please help me to solve this issue.
Thanks.

txtid.Text should be: txtid.text (note lower case "t" in
.text).
If that doesn't work, it would be helpful to see the context
where these two lines are located.

How to determine line count in single multiline textbox

I have data that comes out of a sql db text field that already has line breaks and paragraph breaks. I would like to determine how many lines this will be (w/ line wrapping on) so that I can say if over 20 lines font = 12 pt. etc. How do you determine how many lines there are in a multiline textbox? In .net a textbox can be called w/ .linecount to get the # of lines.
How can I accomplish this in Crystal Reports?
Any help would be appreciated.
Dave

That would work if we had full lines of Text. The problem is that we have line breaks and paragraphs which would prevent lines from being full. Here is an example:
My name is Dave.
I went to the store today and bought some bread, lunch meat, juice,
and wine.

The middle section could be x lines long. But as it grows I need to shrink the font since there is a finite amount of height for the textbox.
Thanks for the idea,
Dave

Sum datagrid column values

I am looking for a way (action script code?) to sum datagrid
column values.
I am using Flex2 with Cold Fusion MX7.
I populate a DataGrid by setting dataprovider to the result
of a Coldfusion query.
(this.masterList.dataProvider = event.result as
ArrayCollection;)
This all works fine.
The masterList datagrid has debit, credit, and unitcost
columns. I want to sum those columns individually, and display the
results in text boxes in another panel.
I could run a Coldfusion query to return the sums, but would
like to do it on the client side with action script.
I want to sum them everytime I update the datagrid, so need
action code that I can put in the result function.
I am new to ActionScript, and not sure how to loop through
the array collection(and/or) dataprovider and sum the items.
Any help would be appreciated.
Thanks.

Loop through your array..if the arrayCollection was named
myArray;
private sumFunction():Number{
var sum:Number=0;
for(var i:uint=0;i<myArray.lenght;i++){
sum+=myArray
.debitValue;
return sum;

Suppressing a line if the sum of a value = 0 in a group footer

How do i suppress a line if the sum of a value = 0 in a group footer
I have tried this this formula in the section expert - Sum ({RM_INV.QUANTITY}) = 0
will not work.

Hi Dana,
The sum function needs to include the group you have your total in like:
Sum ({table.FIELD1}, {RM_INV.QUANTITY}) = 0
{table.FIELD1} would be the field you are grouping on. Your formula was summing the grand total for RM_INV.QUANTITY.
Thanks,
Brian

How to sum a column value using CAML Query?

Hi All,
I would like to sum the column value using CAML qeury. Actually in my list, I have two column "Projects Name" and "Number of Issues". Now need to get sum of "Number of Issues" column. How to achieve in CAML Query.
Thanks in advance!

Hi Sam,
it looks like you can use your current view based agregation, otherwise it is not possible(
http://msdn.microsoft.com/en-us/library/ms467521.aspx) and you need to work on custom bit on this requirement.
use the below link and create a view element as described and see if that works for you
Aggregations Element

How to read multiline element values to a table

Hello every one,
I am facing a problem while reading multiline element values for workflow container.

DATA: lt_url TYPE STANDARD TABLE OF ZHRESS_URL WITH HEADER LINE.
CALL FUNCTION 'SAP_WAPI_READ_CONTAINER'
        EXPORTING
          workitem_id                    = '476329'                            "for instance i have hard coded the value
         LANGUAGE                       = SY-LANGU
         USER                           = SY-UNAME

swc_get_table wf_container 'URL' lt_url.
the above element URL is multiline structure(ZHRESS_URL).
Request your guidence.
Thanks,
Krish.

Hello,
Just look in SIMPLE_CONTAINER, you'll see mutiple entries if there's a table, eg:
ADDRESSSTRINGS                   USSMITHJ
ADDRESSSTRINGS                   USJONESB
You can just read them using normal ABAP.

Using textbox value in a spreadsheet formula

Hi,
I have added an Active-X textbox to my spreadsheet and would like to use the textbox value in a spreadsheet formula. Somehow, the formula does not accept the textbox name as a parameter.
Textbox name: foo
Formula: =foo + 1
Does Excel support using Active-X control values in spreadsheet formulas?
Thx
Carsten

Hi Carsten,
Not directly, you have to assign a cell with the LinkedCell property which you can use in your formula.
